Tolerance is one thing that some people definitely lacking in the world. I cannot say whether they've hear about it. It doesn't matter what it is, but they don't understand. They don't want to try it, they only comment, they lament. Can we call it stupidity? Or is it just ignorance? Some settings are only outdated and in this fact I find it easier to accept. There are old people, well. At that time many things were different and confuse these old people. But intelligent people you would like to suggest a little more understanding and even expectation. Unfortunately, in vain....
